Specification of Letters Patent. Patented Sept. 23, 1919.

Application filed January 13, 1919. Seria1 No. 279,806.

To all whom it may concern:

Be it known that I, Fnnnnnrcx I. CAN- NON, a citizen of the United States, residing at Bedfo'rd, in the county of Ouyahoga an tate of Ohio, have invented certain new "and useful Improvements in Pumps, of

which the followinis a specification.

This inventlon re ates to improvements in pumps and is more particularly deslgned for use in vending oils or other liquids d1- rectly from barrels or other containers, The

the accompanying 'draw%s,

primary object of the invention is toprovide a simple and efi'cctive device or apparatus of the character set forth, that can be connected with a barrel Or other con-- tainer for the purpose of drawing the liqu-idfrom said container and delivering it as desired.

With this and other apparent objects inview, the invention consists in the construction, combination and arrangement of the parts hereinafter described and particularly pointed out in the ap nded c aims when cbmpared or considers in connection-with which are made a, part of the speci cation, similar characters of reference being employed to designate wrresponding In the said drawings igure 1 1s a sectional elevation of an embodnnent of the imroved pump, showing .its. application .to a

arreL' i I Fig. 2 is a. plan section taken on line 2-2, Fig. 1, and Fig. 3 is a, section taken on line 3-3,Fig.'1.

Fig. 4; is an outline elevation 11lustratmg a modification of a portion of the'pumping mechanism, and Fig. 5 is a fragmentary," view fthe modification in direction of airrow, Fig. 4, and showing the piston and connecting rod in a different position.

A pump provided with my improvement 'will include a cylinder 1 provided with a. plunger 2, which has a reciprocatmg movement in said cylinder. The hftmg of the longer serves to draw ase, 011, orother liquid from a container through the pipe '3 into the cylinder, and when depressed it forces the-liquid, thus previously admitted, out of the cylinder through an outlet pipe 4, leading to any desired point of discharge, provision being made at 5 for the attachment of hose,'not shown.

While the elements above mentioned and their operating means are more or less alfactors in the operation of the improved pump. The improvement however lies in the novel arrangement and operation of the lower parts includin the valves and their co-action'with the said common elements.

The base or cylinder support 6 is adapted to rest on'the container B and is provided with a pipe 3 that depends into said container, as shown in Fig. 1. A chamber 7 is rovi'ded in the member 6, said chamber be mg in communication with the interior of I the'cylinder 1. A secondary chamber 8 also communicates with the cylinderthrough the port 9. The chamber 8 is connected with theinlet pipe 3, and ports 10 connect chamher 8 with chamber 7. nects with chamber 8 abovethe ports 10. A valve member 11, preferably hollow as shown, is provided. Said member is adapt-g The outlet 4 conedto slide vertically in the chamber 8, and

is actuated by the action of the plun er 2&-

In the embodiment illustrated in *igs- 2 and 3, the plunger-2 is mounted on the lower end of a vertical shaft or piston rod '12, between the fixed collars 13 and 14, suit able ball-bearings 15 being provided to allow the to turn freely in the plunger. Thepiston'rod12 extends through the head 16 and is provided with right and. left hand screw-threads 17. A bevel gear 18 is mounted with suitable ball-bearings 19, on the head 16, and the piston rod 12 extends through the bore of said gear. A swiveled segmental projection 20 is provided in the bore of the gear 18, said projection being adapted to'travel in theright and left hand screw threads 17 which intersect each other, and at the end portions they commiinicate in such manner that when the projection 20 it will automatically adjust itself and pass into the other screw-thread, whereby the ro-' reaches the extremity of one screw-thread" motion of the rod 12 imparts a reciproeating-motion tojthe collars 13 and 14, and thus the plunger? 2 is reciprocated. This mechanical movement is not new and has been employed. heretofore in pump construction, therefore'I do not claim it specifically. j

.A companion bevel gear 21 is mounted on th head 16 and is in mesh with the gear 18. 3

. A crank 22 provides means for driving the gears.

When the plunger 2 is raised through the medium of the mechanism above described, the suction lifts'the valve 11, there'- by uncovering the ports 10, and the liquid- When the plunger 2 is depressed, the valve 11 is forced downward, thereby closing the ports and the pipe 3; The mouth 4' is;v

uncovered and communication is established from the cylinder, through port 9 and cham- 10 her 8 to the outlet, and liquid that has reviously been drawn into the cylinder is forced out through the outlet 4; A check valve 23 is provided, said check valve being adapted to open on the downward strokeof the plunger, and to close on the up stroke of said plunger.

l The exact quantity of liquid discharged in each full stroke will be determined by the extent of the plunger movement. The desired quantity being predetermined, the capacity of the cylinder and the length of stroke are calculated, and the pump' is designed and assembled accordingly.

In the modification illustrated in Figs. 4 and 5, the 'valve construction and operation is identical with the preferred form as set forth, but the plunger driving mechanism is different. In this construction the piston rod 24 is reciprocated through the medium a'oof a connecting rod 25 connected with a crank '26 which is driven by a manipulating member 27, the rod 2- being guided bya yoke 28. Y

I do'not limit my invention to the specific construction as illustrated anddescribcd, as

many modifications in structure may be made wit-tin the scope of the claims without departing from the spirit of the invention. i

40 What I claim and desire to secure by Letters Patent is;

.1. In a pump, thecombination of :1 cylinder; a reciprocating piston operating in said cylinder; means for actuating said piston; a base member for the cylinder; an

inlet chamber in the base, comn'iunicating' with the cylinder; an outlet chamber in the base communicating with the cylinder; an outlet duct connected with the outlet cham- 'be'r; a check valve in the outlet duct; an

inlet port at the lower extremity of the outlet chamber; ports from the inlet chamber to thefloutlct chamber below the outlet duct;

a slidable valve fitted in the outlet chambet, saidn'alvc being actuated by the suction an compression caused by the reciprocating movement of the'piston, thereby opening the ports that communicate 'with the inlet chhinberand close the outlet duct no on the' suction"stroke,' and close "the 'inlet ports and open the outlet duct on the alternatejcompresswnstroke."
